Virtual Bonding in Ethernet Transmission Wireless Backhauled Links

In order to achieve higher throughput and robust redundancy, bonding ports has been a widely-used technique in wired networking since a long time. With the evolution of 5G, deployment of wireless backhaul links are on the rise, since they require less infrastructure. A single wireless link throughput is limited due to its hardware capabilities, therefore bonded links can be a suitable alternative to provide higher throughput, while keeping same infrastructure. Radios in wireless backhaul links may not be present in the same premises, which demands smart techniques to bond the wireless backhaul links. This paper presents a novel approach of virtually bonding different wireless backhaul links to provide a single control plane for the north and south bound devices for control plane, Management and Data Plane Protocols. Additionally, this approach will scale the extension of Layer 2 and Layer 3 domains of a network, along with a reduction in the manual configuration. Our simulation results show that our approach increased Transmission Control Protocol (TCP) throughput by 59.5% and 61.29% in one and two links scenarios respectively.
